You'll need to flash stock ROM or atleast secro.img to regain baseband.
Did you recently flash the phone? If yes, factory reset the phone in settings > security > factory reset then check if baseband will be valid.

If am to flash then there is a challenge because it's not an original Samsung.
Can i use any other firmware as long as it's MT6580? I can't find the firmware the phone is a clone.
When i go to "about phone" it shows j7,
But when i checked using droid tool it shows&nbsp; model as j57. Also on the back cover model: J57 now am confused which is which.
Any help

It's not an original Samsung device as you stated, you have to first of all take a backup of the current firmware using this guide https://forum.hovatek.com/thread-13347.html then you are to flash nvram and nvdata from an mt6580 phone using the scatter file you got from the backup you did.
